Supermax Law and Legal Definition

Supermax is a security prison cell used to house a dangerous prisoner. Prisoners in supermax are kept in solitary confinement and under constant surveillance. They may need to remain in their cells twenty three hours a day without a television, radio, or other prisoner contact, eat meals alone which are slid into the cells through slots in the doors, and wear shackles when exercising and showering. The average stay for a supermax prisoner is 16-18 months.
